Gypsies and other travellers in the UK tend to live outside the cities, Black and Asian people tend to live in the cities, so occasions for contact between them are relatively uncommon.

I remember when I was a social worker I had a black colleague who had occasion to work with some travellers with a disabled family member - she said that she always felt that they just saw her as another housedweller and official, with those being the significant differences, rather than anything to do with colour or that stuff.
